Dear David
It would really help others out if you added a profile to your signature. Like mine at the bottom. then we know which version of AC and PM you are using and what system you are on.
The toggle was still there in 8.0. It got changed in 8.1. In fact, the arrow keys in 8.1 were completely reprogramed from what they were in 8.0. I had to go through and set them back the way I was accustomed.
Look a bit closer at the usability of 8.1's keys. You will find that nearly all the commands and tools are accessible from a single key stroke. (takes me back to 1993 when I was using Architrion). In 8.1 you can use the 1 key to get the selection tool, the S key to change your snap tool and the P key to change the type of constraint setting tool. Plus there are soooo many more.
This might have been there in 7.0 or 8.0, I am not sure as I upgraded from 6.5 to 8.1. It is nice to have these features. Hard to remember them all, but nice to have them there.
